This invention relates to a new apparatus for carbonating beverages-thatis to say, for chargingareceiver or condenserunder pressure with amixture of gas and water, such mixture being used in the manufacture ofaerated beverages of all kinds.

The invention consists, principally, in cornbining a hollowreciprocating frame with the receiver or condenser and with a stationaryhollow plunger, so that by reciprocating said frame a pumpingand also acompressing action will take place, the frame being balanced by theliquid that passes through it.

It also consists in combining with the reciprocating hollow frame abovementioned a.l reciprocating agitator within the condenser or receiver,for the purpose of thoroughly distributing the gas in the water andagitating the latter within the receiver.

The invention also consists in a new construction of the frame of theapparatus, which is hollow, and which in one continuousstructurecontains the bottom ot' the receiver, the supports of theoperating-shaft, and the supports for the stationary plunger. All theparts exposed to the beverage in the apparatus are lined with block-tin,and the agitator-shaft is jacketed with pure silver, so as topreventcontarnination of the liquid.

The invention also consists in the new arrangement of parts forlubricating the vertically-reciprocating frame, and in many details ofimprovement, which hereinafter are more fully pointed out.

In the accompanying drawings, theletterA represents the frame of theapparatus.

B is the stationary plunger, held inthe lower part ofthe frameAinavertical position. The jam-nut C, screwed upon the lower end of thestationary plunger B and bearing against the bottom of the frame A, asin Fig. 1, holds the stationary plunger in place, said stationaryplunger having a flange, a., that rests on top of the cross-piece b ot'the i'rameA, against the bottom of which cross-piece the nutG presses.

The frame A is tubular throughout, of proper height and strength, andis, at its top, formed into a plate, d, which plate constitutes thebottom plate ot' the receiver or condenser E. At the proper height theupright tubes of the frame A are connected by horizontal tubes A',(shown in Figs.1 and 5,) and on these horizontal tubes A are thebearings e for the driving or operating shaft V, as indicated in Fig. 1.This shaft V has, in line with the posts of the frame, a crank, j',which crank connects by a forked rod, O, (clearly shown in Fig. 2,) withoutwardly-projecting trunni ons g, that are rigidly attached to thereciprocating vertical cylinderD. Thisreciprocatingcylinderembraces andlits, even in its most elevated position, the upper portion ofthestationary plunger B, as is clearly indicated in Figs. 1 and 2, so thatwhen the shaft V is revolved by suitable machinery the cylinder D willbe reciprocated up IOO and down, sliding, in so doing, along thestationary plunger B. This stationary` plunger B is hollow, and has atits lower portion the suction-valve U, which is more clearly shown inFig. ll-that is to say, a valve which' held down upon its seat'by asuitable spring or weight.

From under the valve-seat ot the suctionvalve U extends a pipe,U2, to acock, XV. (See Figs. 1,1 and l2.) This cock is a two-way cock, and soarranged that it can throw the pipe U2 into connection with two branchtubes, U3 and Ut. One of these tubes-say the tube U3- connects with thegas-reservoir, and the other, U4, with the water-reservoir.

The cock W can be turned by its handle (see Figs. 10 and 1l) so as toestablish communication between pipesUand Uand also between pipes U4 andU2, as in Fig. 12, or between one of said branches and the pipe U2 only,ormore with one ot' said branches than with the other, as may bedesired, so that the attendant will always be able to gage, by settingthe cock W, the requisite proportionate supply of gas and water to thestationary plunger.

The vertically-reciprocating cylinder D is hollow throughout its length,and connects at its upper end with a quadrangular hollow frame, D2,which in turn, at its upper end carries the vertical pipe D3, thatpasses upward through the center of the plate d, a suitable stuting-boxfor the tight fitting of the pipe D3 in the aperture of the plate dbeing provided, as shown at h. At the'junction of the cylinder D withthe lower horizontal arms of the tubularframe D2, is placed thedischarge valve L, (more clearly shown in Fig. 13,) which valve also isseated in a downward direction by the action ot' a suitable spring orweight. The upper end of the pipe D3 is perforated within the receiveror condenser E, as shown at t' in Fig. l, and still more clearly inFigs. 6 and 7.

It will be readily understood that, aproper supply ot' water and ot' gasbeing opened to the hollow stationary plungerB and the shaft V beingrevolved, the cylinder D will act as a pump in connection with thevalves U and L and with the stationary plunger B, for in ascendin g thecylinder D will suck the valve U open, leaving the valve L closed, anddraw water and gas upward into the plunger B and cylinder D, and indescending the cylinder D will cause the valve U to be closed and thevalve L to be opened, and the contents of the cylinder D to enter thehollow arms of the frame D2. As the cylinder D now again ascends, thevalve L will immediately close and prevent the return iow of anythingthat is already in the frame D2 or above it, and a new supply will thenbe sucked into the cylinder D, and, on redescending, transferred to theframe D2, Src., -thus causing the vessel E to be charged with a mixtureof gas and water in the requisite proportions, ter the cylinder shallhave which mixture, afbeen properly filled,

will, by the continued reciprocating action of the cylinder D and itsframe D2 and pipe D, be condensed in the vessel E to the necessarydegree, a suitable pressure gage, (lr, being Yplaced upon the receiveror condenser E, to indicate when the desired degree of compression hasbeen reached. A suitable safetyvalve, S, is also placed either into thebottoln of the vessel E or into any other portion thereof. Finally, thecontents ofthe vessel .E may be withdrawn through a pipe, It. 'l is aglass water-gage` attached to the vessel E, to indicate the height ot'water therein.

For a proper guidance ot' the vertically-reciprocating tubular frame D2in the frame A, I provide the posts of the frame A on their inner sideswith guide-railsj, (see Fig. 5,) which are preferably grooved on theircontact-faces with thc frame D2, so as to prevent lateraldisplacelnentof said frame duriugits up-anddown motion. The frame D2 is,at its upper corners, provided with suitable oil-cups, l, whichdischarge through inclined passages l2 along the outer edge of the frameD2, so as to lubricate the contact'surl'aces ot' the frame Dz, and railsj. Superfluous lubricating material is caught in drip-cups m, that aresuspended from the lower corners of the frame D".

The tube D3 carries within the vessel E the agitator' or agitators F,three such agltators being indicated in Fig. 1; but a greater' or lessnumber of them may be used. These agitators F are attached to a shaft,F2, which is se cured to theupper'end of the pipe D, as shown in Fig. l,and more clearly illustrated in Fig. 6. Each agitator F is composed oftwo parts, to wit, a lower plate, n, and an upper plate, o. rEhe lowerplate, a, which, by preference, is cup-shaped, as in Fig. (i, reaches tothe shaft F2 or its jacketing, and is of less diameter than the upperplate, o. The upper plate, o, is annular, its inner circum ference beinglarger than the outer circumference of shaft Fz or its jacketin g, thusleaving au open space, 02, between the plate o andthe shaft, suitablebraces 'being, of course, provided for maintaining the annular plate 0on the shaft. The lower faces of the two plates n ando are provided eachwith one or more spiral ribs or volutes, which, as the agitator descendsduring the reciprocating action of the carrying-pipe D3, cause achurning action of the water, and catch and distribute the gas in thewater which they agr tate, thus causing the necessary intimatecommingling of gas and water within the receiver E.

This apparatus works continuously, and supplies gas and water to thereceiver in the proper proportions, and condenses the mixture in thereceiver. More perfect results will be obtained from it than by anypreviously-known apparatus.

All the parts in the machine that are ex posed to the. beverage arelined with blocktin, which is indicated in tlie drawings by the heavyblack lines on the inner faces ot' the IOO IOS

The valve L can be easily reached by 1inscrewing the cap M, that isplaced over it, as shown in Fig. 13, said cap carrying also aguide-tube,p, in which the stern of the valve L is received; andmoreover the cap M has, outside of the pipe p, a downwardly extendingtube, r, that reaches and holds the seat s for the valve L, the tube rbeing perforated, as shown in Figs. 13 and 14, to permit the properpassage of liquid through it. The lower end of the cylinder D carries asuitable stuffingbox, t, which is in contact with the stationary plungerB, and prevents escape of liquid or gas between the parts B and D. Theframe D2, being tubular throughout, is always evenly balanced by itsliquid contents. Being united to the forked rod O, the balance is madethe more complete, and all lateral strain or tendency to tilt isavoided.

Nothing herein contained is intended to claim anything shown in LettersPatent granted to me September 3, 1867, No. 68,375.
